Answer:
C.
Step-by-step explanation:
In a triangle, the longest side is opposite to the largest measure of angle. The medium side is opposite to the medium angle, while the shortest side is opposite to the smallest angle.
In ∆GHI,
✍️m<G = 95°, it is opposite to
<G is the largest angle, therefore, is the longest side.
✍️m<I = 180 - (95 + 38) = 47°.
<I is opposite to
<I is the medium angle, therefore, is the medium side.
✍️m<H = 38°, it is opposite to
<h is the smallest angle, therefore, is the shortest side.
✅This means:
Answer:
a)
b)
3,814,698
c)
16.08 weeks
Step-by-step explanation:
a)
The question presented here is similar to a compound interest problem. We are informed that there are 400 rice weevils at the beginning of the study. In a compound interest problem this value would be our Principal.
P = 400
Moreover, the population is expected to grow at a rate of 150% every week. This is equivalent to a rate of interest in a compound interest problem.
r = 150% = 1.5
The compound interest formula is given as;
We let y be the weevil population in any given week x. The formula that can be used to predict the weevil population is thus;
b)
The weevil population 10 weeks after the beginning of the study is simply the value of y when x = 10. We substitute x with 10 in the equation obtained from a) above;
Therefore, the weevil population 10 weeks after the beginning of the study is approximately 3,814,698
c)
We are simply required to determine the value of x when y is
1,000,000,000
Substitute y with 1,000,000,000 in the equation obtained in a) above and solve for x;
